Benefits of technology

"The present invention provides a desalinating process that involves freezing sea water and separating salt from ice cubes using an external force. This process has advantages such as less manufacturing steps, quickness, higher fresh water production percentage, practicability, and cost effectiveness. Additionally, this process can be applied to both large-scale desalination and homes."

Problems solved by technology

It is known that water is gradually becoming a rare source in recent years due to population increase, pollution in rivers and lakes, excessive logging of rain forests, environmental disasters, green house effect, etc.
As such, desalination has become an important issue.
But its production is low.
But it also can consume much energy.
Moreover, maintenance of boilers is labor intensive.
In brief, the cost of prior desalination is very high, thus limiting the applications of desalination.
As such, ice in the ice bar will become tasteless in subsequent suctions.
As a result, a structural strength of the sugar and ice compound is very weak.
Hence, ice in the ice bar will become tasteless in subsequent suctions.

Embodiment Construction

[0014]Referring to FIG. 1, there is shown a desalinating process in accordance with a first preferred embodiment of the invention. The process of FIG. 1 begins in step 10, freeze sea water by a vacuum refrigerating method in which the purified sea water is frozen as ice cubes of sea water. In step 20, exert a centrifugal force on the ice cubes of sea water to separate salt therefrom because salt molecules and water molecules are formed as ice cubes of sea water having a loose structure and salt has a larger specific weight as compared with that of water. In brief, the characteristic of the invention is that salt molecules can be easily separated from ice cubes of sea water by applying an external force thereon. In step 30, store salt and ice cubes of fresh water in different places in which ice cubes of fresh water is formed by removing salt from ice cubes of sea water. In step 40, melt ice cubes of fresh water to produce drinkable fresh water and store the separated salt for future...

Abstract

A desalinating process is disclosed. The process comprises freezing sea water as ice of sea water, exerting an external force on the ice of sea water to separate salt therefrom for converting the ice of sea water into ice of fresh water, storing the salt and the ice of fresh water in two different places, and melting the ice of fresh water to produce drinkable fresh water.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to desalination and more particularly to an improved desalinating process.[0003]2. Description of Related Art[0004]It is estimated that there are about 1.4×1,018 tons of water on earth in which about 97.5% is salty sea water and the remaining about 2.5% is fresh water. As to fresh water, about 98% thereof exists on North and South Poles and the Iceland. It is known that water is gradually becoming a rare source in recent years due to population increase, pollution in rivers and lakes, excessive logging of rain forests, environmental disasters, green house effect, etc. As such, desalination has become an important issue. Conventionally, desalination is done by either heating sea water by means of solar energy or distilling sea water by means of boilers. For the former technique, it can save energy. But its production is low. For the latter technique, it can produce fresh water in a large sca...
